LooK non WINDOW scn'nnns AND THE L KE Application filed January 22, 1930. Serial No. 422,572.

This invention relates to a clamp for window screens, such as are used to prevent the passage of insects and the like, when one or the other of the window sashes are raised.

One of the objects of the invention is to provide av clamp by which a pair of frames may be held firmly in adjusted position or released at will.

Another aim is to provide a clamping means for the frames on which the sash is adapted to rest when lowered, thereof preventing rattling, vibration of the screen frame and also of the sash.

These objects are obtained by the novel construction and combination of parts, hereinafter described and shown in the accompanying drawings, forming a component part of the disclosure, and in which:

Fig. 1, is a front elevational view of a conventional type of window, showing an embodiment of the invention as applied thereto.

Fig. 2, is a greatly enlarged fragmentary front view of the screen frame and engaging elements.

Fig. 3, is a sectional view taken on line 3-3 of Fig. 2.

A screen consists of two relatively slidable frames, their outer ends being adapted to be disposed in the window sash runway, and to fill the space between the sill and raised sash, the frames being alike in height as will be understood.

The rear frame 5 may have uniform upper, lower, and one side member, the inner member 6 being preferably narrow. Similarly,

the opposite frame 7 is composed of upper,

lower and one side member, the inner member 8 being narrower so as to avoid obscuring vision through the screens, respectively 9 and 10.

The upper element of the sash member 5 may be undercut, as at 11, to receive a button head 12 formed on a shank 13, this shank being provided with an anchoring device 14: by which it may be secured to the other frame element 7.

However, other suitable sliding connections may be substituted for that shown withoutaffecting the invention.

A thin strip of sheet metal is bent toproduce aflat face 15 spaced slightly from the frame element? .and bent at its lower end at right angles as at 16, thereafter turned upwardly, as at 17, parallel with the face 15. this bent terminal being adaptedto enter the narrow space between the elements 5 and 7 as best seen in Fig. 3.

The opposite end of the strip is bent to produce a'seat *18,-parallel with the element .16, and thereafter bent upwardly at right angles, as at19.

A plate'20 is securely united to the straight outer face of the upstanding element l9,-or if preferred, bemade integral with'it, this plate extending downward in contact with the outer surface of the frame element 5 to a point considerably below the undercut channel 11.

A re inforcing sleeve 21 is secured in the facing 15, tapped to receive ascrew 22 provided with an enlarged manually operated head 23, the point of the screw impinging on the outer surface of the frame element 7 r Fromthe foregoing it will be seen that as the screw 22 and 23 is set up, it will force the elements 17 outwardly at the same time clamping the element rigidly against the outer frame 5, locking the entire structure rigidly together.

Furthermore, the upper sash of the window is adapted to rest on the angular seat element 18, while the screen carrying frames are guided by the raised elements 19 and 20, disposed at the back of the raised sash, preventing movement or vibration of the frames and the window sash as well.

From the foregoing it will be seen that a simple device, inexpensive to manufacture and effective in use, has been disclosed in the preferred form, but it will be obvious that minor changes may be made without affecting the novelty of the structure as disclosed in the following claims, or the spirit of the invention herein described.

Having thus-described the invention, what is claimed as new, and desired to obtain by Letters Patent, is

1. The combination with a screen having two relatively slidable frames, of a looped element engaging one of the frames and having a part enterable therebetween, a right angled extension on the opposite end of said element, a plate united to said extension to reach over the rear of the other frame, and a thumb screw set in the face member of the loop to impinge on the first named frame opposite said plate.

2. The combination with a window screen having a pair of slidably connected frames adapted to fill the space below a window sash 10 and its sill, of a clamp composed of a flat metallic strip having a face disposed trans- Versely over the inner frame, parallel, outwardly extending elements reaching from said face, the lower of said elements bent upwardly to enter between the adjacent frame members, and the upper of said elements eX- tended across the tops of both frame members, an upright at the end of the upper member, a plate fixed on said upright to extend 2U downward in contact with the outer surface of the outer frame, and means for tensionin'g said face against the plate.-

3. The combination with a window screen comprising a pair of slidably connected framesadapted to fill the space below the window sash and its sill, of a clamp composed of a flat metallic strip bent to partially enclose the upper element of the inner frame,a plate combined therewith disposed over the rear surface of the outer frame element, means for clamping the frames in adjustment and-means on said clamp adapted to receive and to guide the window sash immediately over said frames. is!)
